I am selling a single earbud because I lost one shortly after purchasing the pair in March 2025 and had to buy a replacement. This is a single earbud, but it's designed so there's no distinction between left and right; the audio automatically adjusts to the ear it's in. It's an ear cuff style that doesn't block the ear canal, and surprisingly, there's very little sound leakage. The microphone sensitivity and sound quality are excellent, and it has IP54 water resistance, making it suitable for various situations. Please note that because only one earbud is available, some app settings, such as tap control customization, are not fully functional. I used it for a short period, and I don't think there are any noticeable scratches or signs of use on the earbud or the charging case, but please understand that this is a used item. - Color: Black - Design: Open-ear / Ear cuff style - Charging Case: Supports wireless charging - Buttons: Touch control - Up to 10 hours of playback on a full charge, up to 40 hours with the charging case Thank you for looking. #HalloweenOnMercari
